7 Claims.

This invention relates to a book construction particularly useful for check books, coupon books, note books, memorandum pads, etc.; and the invention contemplates a cover construc- 5 tionhousing a bound packet which may, if desired, be removed from the cover and replaced with a new packet.

The general object of the invention is to improve book constructions of this type in various ways, including simplification, reduction of cost, ease of refilling the cover with a new packet, and improved holding of the packet within the cover.

Fig. I is a plan view of a bound packet in ac- 1'5- cordance with the present invention.

Fig. II- is an edge view of the packet shown in Fig. I, the packet having a backing leaf which is shown flexed away from the rest of the packet for the sake of clarity.

20 Fig. III is a plan view of a cover in accordance with the present invention, before the cover is applied to the packet.

Fig. IV is a detail edge view showing one step in the application of the cover to the packet.

25 Fig. V is a detail edge view showing a later step in the application of the cover to the packet.

Fig. VI is a plan view of the complete book.

Fig. VII is a longitudinal section taken on the line 'I-'! of Fig. VI.

30 Fig. VIII is a detail edge view showing a slightly modified construction of the packet.

In Figs. II, IV, V, VII, and VIII there is the usual difficulty of illustrating edge or sectional I views of sheet material, with the result that 35 various sheets are shown disproportionately thick.

Referring to Figs. I and II, the packet comprises a bundle of leaves I positioned between a backing leaf 2 and a binding strip 3. In this 40 instance the binding strip 3 is part of an extension of the backing leaf 2, which extension passes at 2 around one edge of the bundle of leaves I and laps over on top of the leaves. Suitable means such as staples 4, 5, and 6 are 45 used to bind together the bundle of leaves I,

the back leaf 2 and the binding strip 3. Preferably, these staples are positioned as shown in Fig. I, staples 4 and 5 being at the ends of binding strip 3 and staple 6 being close to the edge 50 of the packet, for a purpose which will be pointed out later. The leaves of the bundle I may be adapted for any desired purpose; and in Fig. I the leaves are shown marked with a line of perforations I so as to provide a series of 55 coupons such as 8, each of, which has a stub such as 9. The coupon 8 may be a deposit coupon, a bank check, or any other form of coupon; and if desired the coupons and stubs may be consecutively numbered as at 8 and 9*, respectively. Preferably, the backing leaf 2 and binding strip 5 3 are of material which, while flexible, is strong and has a degree of body and stiifness such as, for example, heavy manila paper. As shown in the drawing, backing leaf 2 is coextensive with the leaves of the bundle I, but it is not 10 necessary that this backing leaf be either as long or as wide as the leaves of bundle I.

The cover shown in Fig. III may be formed from a single sheet of material and preferably it is suitable cover material having durability and body. The cover has a sleeve portion I2 formed by two flaps I4 and I5 which are overlapped and held together by adhesive. Extending from one end of the sleeve portion I2 is a short section I6 provided with notches I I and I8 for a purpose which will be referred to later.

Extending from the other end of the sleeve portion I2 is a longer section I9 having corners cut away at 20 and 2|, thereby leaving a nose I 9 With some cover materials it is desirable to provide crease or score lines, as indicated at 24, 25, 26, 21 and 28. These score lines are not essential, and with some cover materials the cover is just as good without them.

To apply the cover of Fig. III to the bound packet of Fig. I, the cover is first held with flaps I4 and I5 uppermost and end, portion I6 is slipped under the binding strip 3. The notches I1 and I8 straddle staples 4 and 5, respectively, so that the entire end portion I6 may be inserted under strip 3. Then the cover is folded back toward the bound edge of the packet after the manner shown in Fig. IV. As the sleeve portion I2 of the cover is brought beneath the packet, backing leaf 2 is flexed and inserted into the sleeve, as shown in Fig. V. Sleeve portion I2 is brought up against the back of the bundle of leaves, and section I9 is then folded around the edge of the packet opposite to the bound edge, as is shown in Fig. VIII. Nose I9 of section I9 may be inserted under end portion It so that it too is held beneath the binding strip 3. Thus the cover is frictionally held in closed position about the packet without the necessity for any extra snaps, catches or the like. With a narrow book it is often desirable to place staple 6 thru the bundle of leaves I before part 2, 2, 3 is applied, so that this staple does not secure binding strip 3, and cover ends I6 and I9 can be inserted more easily. If desired the cover may be provided with an aperture 4|, through which the serial number of the top coupon may be viewed without opening the book.

When the leaves of the packet have all been used up, the old packet may be removed by withdrawing the backing leaf 2 and manipulating the cover in a manner reverse to that described for applying the cover to the packet. A refill packet may then be inserted into the cover. It will be found that the packet is very securely held in the cover and that in handling and using the book there is no danger of the packet dropping out of, or shifting its position in, the cover.

While it is convenient to form the binding strip 3 by an extension from backing leaf 2, the binding strip may be a separate piece of material, as shown in Fig. VIII. In Fig. VIII the backing leaf 2 terminates at the bound edge of the packet, and the binding strip 3 is a separate strip applied on top of the packet.

In compliance with the patent statutes, I have shown the best forms in which I have contemplated applying my invention, but it will be realized that various changes and modifications are possible within the scope of the claims hereto.

I claim:

1. In a book: a packet comprising a binding strip, a backing leaf, and a bundle of leaves positioned between the binding strip and the backing leaf, the packet having an edge adjacent to which the binding strip, leaves and backing strip are bound together; and a cover of sheet material secured to said backing leaf, the cover extending around the bound edge of the packet and having an edge portion positioned beneath said binding strip.

2. In a book: a rectangular packet comprising a binding strip, a backing leaf, and a bundle of leaves positioned between the binding strip and the backing leaf, the packet having an edge adjacent to which the binding strip, leaves and backing strip are bound together; and a cover of sheet material secured to said backing leaf, the cover extending around the bound edge of the packet and having a first edge portion positioned beneath said binding strip, the cover also extending around the opposite edge of the packet and having a second edge portion removably held by friction beneath said first edge portion.

3. In a book: a packet comprising a binding strip, a backing leaf, a bundle of leaves positioned between the binding strip and the backing leaf, and metal binding means piercing said strip, leaves and backing leaf adjacent to one edge of the packet; and a cover of sheet material detachably secured to said backing leaf, the cover extending around the bound edge of the packet and having an edge portion removably held by friction beneath said binding strip.
